Abstract
Using modern multiloop calculation methods, we derive the analytical expressions for the total cross sections of the processes with or at arbitrary energies. For the first two processes our results are expressed via classical polylogarithms. The cross section of is represented as a one-fold integral of complete elliptic integral and logarithms. Using our results, we calculate the threshold and high-energy asymptotics and compare them with available results.
